CVE-2026-80938

In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt7615: avoid waiting for mac work under the mt76 mutex

mt7615 suspend() acquired the mt76 mutex and then called cancel delayed work sync() on mac work. mt7615 mac work() acquires the same mutex via mt7615 mutex acquire() at the top of the worker, so if mac work is already running and blocked on the mutex, the suspend path deadlocks waiting for the work it holds the mutex against.

Flush scan work and mac work before taking the mutex, matching the suspend paths in mt7921 and mt7925. scan work only takes the mt76 spinlock, but moving it keeps the sequence consistent. This also keeps mac work from running over an already suspended HIF, which the previous split (async cancel under the lock, sync cancel after release) would have allowed.
